discovery(testing): test_causal_reasoning.py fails to import think_causally — module or function missing

[mrveiss]

Discovery

tests/test_causal_reasoning.py fails at collection with an ImportError for think_causally. The function or module it imports from does not exist (or has been renamed/removed).

Pre-existing failure — confirmed by agent during #4661 implementation.

Fix

Locate where think_causally was supposed to be defined, either restore it or update the import in the test file to match the current symbol name.

Found during

Implementation of #4661 (AUTOBOT_*_ENDPOINT env vars fix).

✅ Closed — fix merged in PR #4735

Commit: 58e4877 — fix(testing): add think_causally + ThinkCategory.CAUSAL_ANALYSIS

Acceptance Criteria Met:

• ✅ ThinkCategory.CAUSAL_ANALYSIS added to enum in agent_loop/types.py
• ✅ think_causally() function added to agent_loop/think_tool.py with matching prompt
• ✅ CausalErrorAnalyzer._parse_causal_result fixed to use conclusion field first
• ✅ 15 passed, 1 xfailed (llama_index not in test env — matches existing pattern)
